Matthew, You might want to look at function read.table.ffdf in the ff package, which can read large csv files in chunks and store the result in a binary format on disk that can be quickly accessed from R...

I am running into problems calling the library function nlme from within another function. Basically,the following function (with v a list containing data and initialization values) > testfunc function(dat=v) { test<-nlsList(result~a+(b-a)/(1+(conc/(c...

Hi, Andrea, This page might be helpful for you: https://www.bioconductor.org/developers/package-guidelines/#vignettes. The "Write R extensions" manual also explaines how to write a citation file: https://cran.r-project.org/doc/manuals/r-release/R...

Hi, I am working with two shapefiles in R; one is a point.shp the other is a polygon.shp. Now, I would like to intersect/join/attach all the values from the polygon to the table of the point...

I am going to document a 10.000 lines of R code project. Before reinventing the wheel, has anyone written a function that analyzes dependencies between R functions? I am thinking of output like caller1 calee1 caller1 calee2 caller1 : caller2...

Kjetil, your suggestion is fine for small data sets, but dist() has o(2) memory and calculation time requirements. I assume that Ryszard wanted a function that does ONLY calculate distances between all combinations of two sets of data rows...

I want to layout on screen a graphic bigger than the screen (width=16.53543, height=11.69291) but strwidth() and strheight() give wrong results. > x11(width=42/2.54, height=29.7/2.54, pointsize=12) > plot(1,1...

Hi, I am facing a problem with the legend, I don?t know how to use the fill option in the legend in order to achieve the same standard gray levels that are plotted. Sorry for this easy one, but...

Hi everyone. I remember some very interesting and professional-looking R projects that somehow involved geographical maps. Now that I'd like to work with maps myself, let me ask you this question: Which of the packages that are currently...

Dear list, As I have read (Bolker et al. 2009 TREE), the Wald Z test is only appropriate for GLMMs in cases without overdispersion. Assuming we use family=poisson with lmer and tackle overdispersion by incorporating an individual random effect...

I think this is a moment to lean back from daily business, details or whatsoever and appreciate the impressive achievment of Ross, Robert and the R-core team. Incredible! They created an impressive and extremely useful software, for teaching, research...

Dear R-sig-ecology group, is there a way to use two self-made dissimilarity matrices for the left-hand side (LHS) and right hand side (RHS) in vegan functions such as capscale or adonis? I created those matrices in...

Jeff, R has 'environments' as a general mechanism to pass around objects by reference. However, that does not help with most functions like 'apply' which take arguments other than environments. > I'm familiar with FF and BigMemory, but are there...
